Photo for species Viburnum_lantanoides

Viburnum lantanoides is used medicinally, and its fruits are edible, reportedly tasting better following a frost. Its fruits are also a preferred food of ruffed grouse, brown thrashers, cedar waxwings, squirrels, and chipmunks.

Viburnum lantanoides

hobblebush
What does this species look like?
What does this species look like?: 

Hobblebush is a sprawling, deciduous shrub, with main stems ascending or erect with spreading, often pendulous, branches, growing 3 to 12 feet tall. The white to light yellow flowers are grouped into showy, flat-topped clusters, each cluster having two types of flowers: larger, showy, flowers on the outside edges of the cluster that are sterile; and tiny, more central flowers having both male and female parts that are insect- and possibly hummingbird-pollinated.

Hobblebush is found in bottomlands and shaded ravines, thickets, and cool, mesic to moist woods. It prefers well-drained soils. This species is shade tolerant.

Why observe this species?

Hobblebush is a USA-NPN regional plant species. Regional species are ecologically or economically important but are distributed more locally than calibration species. The NPN integrates these observations to understand better plant responses within the different geographic regions of the nation.

Special Considerations for Observing

If drought seems to be the cause of leaf color or fall for a plant, please make a comment about it for that observation.

Which phenophases should I observe?
Leaves

Do you see...?

Breaking leaf buds
One or more breaking leaf buds are visible on the plant. A leaf bud is considered "breaking" once a green leaf tip is visible at the end of the bud, but before the first leaf from the bud has unfolded to expose the leaf stalk (petiole) or leaf base. For Viburnum lantanoides, the naked leaf bud is considered "breaking" once the bright green leaf surface is visible between partially uncurled leaf edges, but before the leaf edges have fully uncurled to create a relatively flat leaf surface'

How many buds are breaking?

Less than 3;3 to 10;11 to 100;101 to 1,000;1,001 to 10,000;More than 10,000

More...

Leaves
One or more live, unfolded leaves are visible on the plant. A leaf is considered "unfolded" once its entire length has emerged from the breaking bud so that the leaf stalk (petiole) or leaf base is visible at its point of attachment to the stem. Do not include fully dried or dead leaves. For Viburnum lantanoides, a leaf is considered "unfolded" when the leaf edges have fully uncurled to create a relatively flat leaf surface'

What percentage of the canopy is full with leaves? Ignore dead branches in your estimate.

Less than 5%;5-24%;25-49%;50-74%;75-94%;95% or more

More...

Increasing leaf size
A majority of leaves on the plant have not yet reached their full size and are still growing larger. Do not include new leaves that continue to emerge at the ends of elongating stems throughout the growing season.

What percentage of full size are most leaves?

Less than 25%;25-49%;50-74%;75-94%;95% or more

More...

Colored leaves
One or more leaves (including any that have recently fallen from the plant) have turned to their late-season colors. Do not include fully dried or dead leaves that remain on the plant.

What percentage of the canopy is full with colored leaves?

Less than 5%;5-24%;25-49%;50-74%;75-94%;95% or more

More...

Falling leaves
One or more leaves are falling or have recently fallen from the plant. More...

Flowers

Do you see...?

Flowers or flower buds
One or more fresh open or unopened flowers or flower buds are visible on the plant. Include flower buds that are still developing, but do not include wilted or dried flowers.

How many flowers and flower buds are present? For species in which individual flowers are clustered in flower heads, spikes or catkins (inflorescences), simply estimate the number of flower heads, spikes or catkins and not the number of individual flowers.

Less than 3;3 to 10;11 to 100;101 to 1,000;1,001 to 10,000;More than 10,000

More...

Open flowers
One or more open, fresh flowers are visible on the plant. Flowers are considered "open" when the reproductive parts (male stamens or female pistils) are visible between or within unfolded or open flower parts (petals, floral tubes or sepals). Do not include wilted or dried flowers. For Viburnum lantanoides, ignore the large, sterile flowers on the outside of the flower cluster, and watch for the opening of the smaller, fertile flowers in the center'

What percentage of all fresh flowers (buds plus unopened plus open) on the plant are open? For species in which individual flowers are clustered in flower heads, spikes or catkins (inflorescences), estimate the percentage of all individual flowers that are open.

Less than 5%;5-24%;25-49%;50-74%;75-94%;95% or more

Fruits

Do you see...?

Fruits
One or more fruits are visible on the plant. For Viburnum lantanoides, the fruit is berry-like and changes from green to reddish to purple-black'

How many fruits are present?

Less than 3;3 to 10;11 to 100;101 to 1,000;1,001 to 10,000;More than 10,000

More...

Ripe fruits
One or more ripe fruits are visible on the plant. For Viburnum lantanoides, a fruit is considered ripe when it has turned purple-black'

What percentage of all fruits (unripe plus ripe) on the plant are ripe?

Less than 5%;5-24%;25-49%;50-74%;75-94%;95% or more

More...

Recent fruit or seed drop
One or more mature fruits or seeds have dropped or been removed from the plant since your last visit. Do not include obviously immature fruits that have dropped before ripening, such as in a heavy rain or wind, or empty fruits that had long ago dropped all of their seeds but remained on the plant.

How many mature fruits have dropped seeds or have completely dropped or been removed from the plant since your last visit?

Less than 3;3 to 10;11 to 100;101 to 1,000;1,001 to 10,000;More than 10,000
